I am considering purchasing Sublime Text. If I did so I would likely want to use Sublime Text 3 beta since that'll become the new standard and I may as well get used to the newest version.

However I am curious about plugin support.

Are plugins that are currently in Sublime Text 2 compatible with Sublime Text 3? Is there a good library of the commonly-used plugins for Sublime Text 3 already ported and stable? I would like to know before I purchase.
